In the prior art, an electric room is arranged in an end cover at one side of an electric water heater, and a containing cavity is formed between an electric room shell and the end cover so as to arrange all electric elements in the containing cavity. Along with the temperature change in the accommodating cavity in the using process of the water heater, water vapor in the accommodating cavity can be condensed to form condensed water. In some special cases, the inner container of the electric water heater can permeate water, and as the end socket end of the inner container is usually abutted with the electric chamber shell, the permeated water of the inner container can flow into the accommodating cavity of the electric chamber.

Therefore, in order to prevent the condensate water or the water seepage of the inner container in the electric room from affecting the normal operation of each electric element in the electric room, the condensate water or the water seepage in the accommodating cavity of the electric room needs to be drained in time.

the outer sidewall of the housing 100 is provided with a waterproof wall cover 300, the waterproof wall cover 300 is provided with a water outlet 320, one end of the water drainage channel 220 is communicated with the first accommodating cavity 210, and the other end of the water drainage channel 220 is communicated with the outside through the water outlet 320, so that water in the accommodating cavity is discharged to the outside through the water drainage channel 220.

It will be appreciated that the electric room housing 200 is provided at an end of the housing 100, one side of the electric room housing 200 faces the outside of the housing 100 for mounting electric components, and the other side of the electric room housing 200 faces the inside of the housing 100, abutting against the end seal of the inner container 500. The end cap 110 covers at least a portion of the electric room housing 200 to form a first receiving chamber 210 with the electric room housing 200. With the temperature change of the water heater during operation, the water vapor in the first accommodating cavity 210 is condensed to form condensed water, or the water seeping out from the inner container 500 flows into the first accommodating cavity 210.

It should be noted that, the first accommodating cavity 210 may be formed by only connecting the electric room housing 200 and the end cover 110, or may be formed by the electric room housing 200, the end cover 110, and the inner side wall of the housing 100 between the electric room housing 200 and the end cover 110, which is not limited in the present application.

The drain passage 220 is provided such that one end thereof communicates with the first receiving chamber 210, and condensed water or permeated water in the first receiving chamber 210 can flow into the drain passage 220, thereby preventing water from accumulating in the first receiving chamber 210. Because the outer side wall of the casing 100 is provided with the electricity-proof wall cover 300, the electricity-proof wall cover 300 is covered at the electricity-proof wall of the water inlet and outlet pipe 400, so as to form safety protection for the electricity-proof wall and other components of the water inlet and outlet pipe 400. Wherein, the electricity-proof wall cover 300 is provided with a water outlet 320 communicated with the outside, and shower water entering the electricity-proof wall cover 300 during shower can be discharged through the water outlet 320. Therefore, the other end of the drainage channel 220 is communicated with the outside through the water outlet 320, so that the first accommodating cavity 210 is communicated with the water outlet 320, and the condensed water in the first accommodating cavity 210 flows through the drainage channel 220 and is discharged to the outside from the water outlet 320.

Therefore, in the water heater provided by the application, by arranging the water drainage channel 220 communicated with the first accommodating cavity 210 and enabling the water drainage channel 220 to be communicated with the outside through the water outlet 320 of the anti-electricity wall cover 300, condensed water or seeped water in the first accommodating cavity 210 can pass through the water drainage channel 220 and be discharged through the water outlet 320, the situation that the water drainage hole 222 of the first accommodating cavity 210 is directly exposed outside the end cover 110 is avoided, the possibility that impurities such as mosquitoes or dust enter the first accommodating cavity 210 is reduced, and the tightness and the operation stability of the electric room of the electric water heater are improved.

In addition, since both ends of the drain passage 220 are located inside the water heater, the drain passage 220 can be considered to be built in the housing 100, so that the drain hole 222 does not need to be formed on the outer side of the water heater end cover 110, and the overall aesthetic property of the water heater is ensured.

Wherein, as shown in fig. 5, 6 and 7, the drain passage 220 includes a water conduit 221 and a drain hole 222, the drain hole 222 being located on the housing 100 or the electric room housing 200;

In other embodiments, the water conduit 221 may be threaded or glued to the drain hole 222, as the application is not limited in this regard.

The water conduit 221 is communicated with the water outlet 320, so that the condensed water entering the water drain hole 222 can be effectively ensured to smoothly flow to the water outlet 320 of the electricity-proof wall cover 300 and be discharged through the water outlet 320. From the outside of the water heater, the water heater can drain water only through the water outlet 320, and compared with the existing water heater, the water outlet 320 of the electricity-proof wall cover 300 and the water outlet 222 arranged on the outside of the end cover 110 effectively reduce the number of holes on the outside of the water heater, further improve the integrity and the tightness of the whole structure of the water heater, and also improve the use appearance of users.

In some embodiments, as shown in fig. 6 and 7, drain holes 222 are located on electrical compartment housing 200.

It will be appreciated that because the electric housing 200 is closer to the anti-electricity wall cover 300 than the end cap 110, the length of the penstock 221 may be somewhat shortened, saving costs. In addition, the drain hole 222 is disposed on the electrical room housing 200, so that the drain hole 222 is effectively prevented from being exposed outside the end cover 110, and the processing difficulty is lower than the drain hole 222 disposed inside the end cover 110.

In other embodiments, the drain hole 222 may be disposed inside the end cover 110, but the structure of the electrical chamber housing 200 needs to be correspondingly adjusted to avoid the electrical chamber housing 200 from the drain hole 222 inside the end cover 110, so as to prevent interference with normal drainage of condensed water or seeped water; or the drain hole 222 is arranged at the connection position of the end cover 110 and the electric room housing 200, so that half of drain hole 222 structures are required to be respectively arranged on the electric room housing 200 and the end cover 110, and the two structures are spliced to form a complete drain hole 222, so that the installation precision of the electric room housing 200 and the end cover 110 is required to be ensured, and the dislocation of the spliced drain hole 222 is prevented, so that the installation of a subsequent water guide pipe 221 is influenced; the drain hole 222 may be provided in the housing 100, which is not limited in the present application.

In some embodiments, as shown in fig. 5 to 7, a side of the electric room housing 200 facing the first receiving chamber 210 has an annular guide surface 230, and the annular guide surface 230 is wound around a circumferential side of the drain hole 222.

It can be appreciated that the annular diversion surface 230 surrounding the drain hole 222 is disposed on the electrical room housing 200, so as to divert condensed water or seeped water when flowing to the drain hole 222, thereby further improving the accumulation effect of water in the first accommodating cavity 210 and further improving the drainage efficiency of the drain hole 222.

In this embodiment, the annular diversion surface 230 is spherical, so that the annular diversion surface 230 better surrounds the drain hole 222 and is attached to the drain hole 222, and the water collecting effect is better. In other embodiments, the annular diversion surface 230 may be tapered, so as to further improve the diversion effect, the large diameter end of the tapered is wound with the drain hole 222, and the small diameter end is spliced with the water conduit 221, which is not limited in the present application.

It can be appreciated that, after the water heater is installed, the drain hole 222 of the first accommodating cavity 210 is higher than the electricity preventing wall cover 300, so that the water conduit 221 is at least partially inclined, and specifically, the side near the water outlet 320 of the electricity preventing wall cover 300 is lower than the side near the drain hole 222 of the first accommodating cavity 210, so that the condensed water can better circulate, and the drainage efficiency of the drainage channel 220 is improved.

And the hard plastic pipe has higher self structural strength, so that the foaming material can be effectively prevented from being extruded and deformed in the foaming process of the foaming material in the water heater shell 100, and the influence on the smoothness of the inside of the water conduit 221 is avoided.

In other embodiments, a U-shaped section may be further disposed on the water conduit 221, and after the water conduit 221 drains water, a portion of condensed water remains in the U-shaped section all the time, and the U-shaped section is plugged with condensed water to isolate air circulation in the water conduit 221, so as to further improve the tightness of the first accommodating cavity 210.

In addition, as shown in fig. 4 and 5, the electricity-proof wall cover 300 forms a second receiving chamber 310 with the outer sidewall of the case 100, the water outlet 320 is located at the bottom of the electricity-proof wall cover 300, and the second receiving chamber 310 communicates with the outside through the water outlet 320.

It can be appreciated that a second receiving chamber 310 is formed between the electricity preventing wall cover 300 and the outer side wall of the case 100 to receive the electricity preventing wall of the water inlet and outlet pipe 400 and other structures through the second receiving chamber 310. Since there is a gap in the second receiving chamber 310, water easily enters the second receiving chamber 310 during a shower, and the water outlet 320 is provided at the bottom of the second receiving container so that the second receiving chamber 310 communicates with the outside through the water outlet 320, and the shower water in the second receiving chamber 310 can be discharged through the water outlet 320.

Specifically, as shown in fig. 2 and 4, since the bottom surface of the electricity-proof wall cover 300 is obliquely arranged, the water outlet 320 can be arranged at the lowest point of the inclined bottom surface of the electricity-proof wall cover 300, so as to improve the drainage efficiency of the water outlet 320 and effectively avoid water accumulation in the second accommodating cavity 310.

In this embodiment, only one water outlet 320 is provided in the second accommodating cavity 310, but in other embodiments, two or more water outlets 320 may be provided at intervals to further improve the water draining effect of the second accommodating cavity 310, and the air in the second accommodating cavity 310 may be circulated to a certain extent to ensure that the second accommodating cavity 310 is clean and dry, which is not limited in the present application.

In some embodiments, as shown in fig. 6, the case 100 is provided with a through hole 120 communicating with the second receiving chamber 310, and the other end of the drain passage 220 communicates with the second receiving chamber 310 through the through hole 120.

It will be appreciated that since the second receiving chamber 310 is located at the outer side wall of the housing 100 and the first receiving chamber 210 is located within the housing 100, the housing 100 is sandwiched between the first receiving chamber 210 and the second receiving chamber 310. Therefore, in order to realize the communication between the first receiving chamber 210 and the second receiving chamber 310 through the drainage channel 220 and to avoid the drainage channel 220 from being exposed to the outside of the housing 100, a through hole 120 communicating with the second receiving chamber 310 may be formed in the housing 100 to allow the drainage channel 220 to pass through. In order to make the overall structure of the water heater compact and ensure the beautiful appearance of the water heater, the through hole 120 can be arranged in the range of the casing 100 covered by the electricity-proof wall cover 300, so that the through hole 120 is shielded from view by the electricity-proof wall cover 300.

In a specific implementation, the through hole 120 may be a through hole 120 originally provided on the housing 100, through which a power supply chamber line passes; or the through hole 120 specially opened to allow the water drain passage 220, i.e., the water conduit 221 to pass through, the present application is not limited thereto.

Also, in some embodiments, the end of the penstock 221 may be set up at the through-hole 120 such that water flowing out of the penstock 221 drops within the second receiving cavity 310 and flows toward the water outlet 320; the end of the water conduit 221 may be directly connected to the water outlet 320, and may be directly discharged from the water outlet 320, which is not limited.

In addition, as shown in fig. 4, the electricity preventing wall cover 300 is provided with a mounting hole 330, the mounting hole 330 is used for penetrating the water inlet and outlet pipe 400 of the water heater, and the water outlet 320 is used for discharging shower water entering the second accommodating cavity 310 through the mounting hole 330.

It should be noted that, since the electricity-proof wall cover 300 is used to cover the electricity-proof wall of the water inlet and outlet pipe 400 of the water heater to form safety protection for the electricity-proof wall and other components of the water inlet and outlet pipe 400, the electricity-proof wall cover 300 needs to be provided with the mounting hole 330 for the water inlet and outlet pipe 400 to pass through and be communicated with the inner container 500. There is no gap between the mounting hole 330 and the water inlet/outlet pipe 400, so that water may be sprayed or splashed into the second receiving chamber 310 through the gap between the mounting hole 330 and the water inlet/outlet pipe 400 during a shower. Therefore, the water outlet 320 is necessary to be disposed on the waterproof wall cover 300 to prevent the second accommodating cavity 310 from accumulating water, and the water outlet 320 is communicated with the first accommodating cavity 210 through the water drainage channel 220, so that the water in the first accommodating cavity 210 can be introduced into the second accommodating cavity 310 through the water drainage channel 220 and drained through the water outlet 320, and the water heater structure is more compact without providing the water drainage hole 222 outside the end cover 110.
